ASIA-PACIFIC JOURNAL OF CLINICAL ONCOLOGY, Issue 1 2010

Abstract Aim: Primary adenocarcinoma of the appendix is a rare malignancy. This study assessed prognostic factors affecting the clinical outcome in patients with appendiceal neoplasms. Methods: We performed a retrospective analysis of patients who had appendectomies between 1991 and 2007 at five centers in South Korea. Results: Overall 55 patients (19 men, 36 women, median age 61 years) were identified. Of these, 37 (67.3%) were mucinous adenocarcinomas, 14 (25.5%) were intestinal-type adenocarcinomas, and four (7.3%) were signet ring cell carcinomas. The distribution of stages was: 26 (47.3%) with localized disease, five (9.1%) with regional disease, and 24 (43.6%) with distant metastatic disease. The overall 3- and 5-year survival rates among all patients were 72.2% and 64.0%, respectively, with 20 deaths during the follow-up period. In a multivariate analysis, high histological grade (hazard ratio [HR]vs low grade 15.7; P = 0.001) and pathological stage (distant vs loco-regional, HR 6.2; P = 0.021) were independent predictors of overall survival. Of the 34 patients who underwent curative resections of primary appendiceal carcinomas, the 3- and 5-year disease-free survival rates were 66.4% and 53.3%, respectively. The recurrence rate was higher in patients with regional lymph node metastasis (HR vs node negative disease 23.4; P = 0.005) and high-grade tumors (HR vs low grade 6.3; P = 0.029). Additionally, a right hemicolectomy reduced the risk of recurrence (HR vs lesser procedures 0.05; P = 0.005). Conclusion: High tumor grade and advanced stage were significantly predictive of poor survival outcome in patients with primary appendiceal carcinomas. [source]


Immunohistochemical study of the expression of adhesion molecules in ovarian serous neoplasms

PATHOLOGY INTERNATIONAL, Issue 2 2006
Eun Yoon Cho
To clarify possible roles of adhesion molecules including E-cadherin, ,- and ,-catenin, CD44s, CD44v6, CD56, and CD99 in ovarian serous neoplasms, an immunohistochemical study was undertaken for 23 benign, 40 borderline, and 95 malignant ovarian serous neoplasms using tissue microarray (TMA). Significantly reduced expression of E-cadherin, and overexpression of CD44s, CD56, and CD99 were more frequently observed in adenocarcinomas than in benign and borderline tumors. Expression of CD44v6 and nuclear ,- and ,-catenin were detected only in borderline tumors and adenocarcinomas. Reduced expression of E-cadherin was also correlated with high tumor grade (P = 0.03), presence of peritoneal seeding (P = 0.03), and low overall survival rate (P = 0.02). Overexpression of CD44s was significantly associated with high tumor grade (P = 0.04), advanced stage (P = 0.03), and low overall survival rate (P = 0.02). CD56 was increasingly expressed in the case of advanced stage (P = 0.005) and peritoneal seeding (P = 0.001). Nuclear staining for ,-catenin was correlated with tumor progression (P = 0.004) and advanced International Federation of Gynecology and Obstetrics (FIGO) stage (P = 0.02). Only CD44s expression and stage were correlated with overall survival in multivariate study. These results suggest that although E-cadherin, CD44s, CD56, and nuclear ,-catenin immunoexpression seem to be useful prognostic markers for serous neoplasm of the ovary, CD44s expression and FIGO stage are independent prognostic factors.

Correlation of Her-2/neu Gene Amplification with Other Prognostic and Predictive Factors in Female Breast Carcinoma

Abstract: , The purpose of this study was to determine if any relationship exists between Her-2/neu gene amplification and estrogen receptor (ER), progesterone receptor (PR), MIB-1, grade, size and age in female breast cancer. Five hundred and eighteen female patients with invasive breast carcinoma, 390 ductal and 128 lobular, in which assessment of Her-2/neu amplification by fluorescence in-situ hybridization (FISH) has been performed, were reviewed retrospectively. Each patient was further assessed for ER, PR, MIB-1, grade, size and age at diagnosis. Chi-square analysis was then used to correlate the above observations. Overall gene amplification was seen in 76 (15%) of the cases, 68 (17%) were ductal and 8 (6%) were lobular. Her-2/neu gene was amplified in 37 (10%) out of 379 ER positive cases and in 39 (28%) out of 139 ER negative cases. Her-2/neu was amplified in 22 (7%) out of 301 PR positive cases and in 54 (25%) out of 217 PR negative cases. Amplification occurred in 18 (8%) out of 222 negative MIB-1 cases and amplified in 58 (20%) out of 296 positive cases. Amplification was seen in 5 (10%) out of 49 grade I tumors, 17 (12%) out of 143 grade II tumors and 54 (27%) out of 198 grade III tumors. Lobular carcinomas were not graded. Amplification was present in 52 (15%) out of 346 T1 lesions, in 17 (13%) out of 130 T2 lesions, in 5 (17%) out of 30 T3 lesions and in 2 (17%) out of 12 T4 lesions. Her-2/neu was amplified in 67 (14%) out of 467 woman 41 years and older, and in 9 (18%) out of 51 women 40 years and younger. Comparison of these frequencies using chi-square test revealed statistically significant correlation between Her-2/neu amplification and ductal versus lobular carcinoma (p < 0.0003), ER (p = 0.0001) and PR (p < 0.0001) negative tumors, over-expression of MIB-1 (p < 0.0005) and high tumor grade (p = 0.0009), while size of the tumor (p = 0.08) and age of the patients (p = 0.67) were not statistically significant. Correlation was found between Her-2/neu amplification and tumor type, high histological grade, ER and PR negative tumors, and high proliferative MIB-1 index. No correlation was found between size of the tumor and age of the patient with Her-2/neu amplification. [source]


Prognostic factors for patients with localized soft-tissue sarcoma treated with conservation surgery and radiation therapy

CANCER, Issue 10 2003
An analysis of 1225 patients
Abstract BACKGROUND Prognostic factors for patients with soft-tissue sarcoma who are treated with conservative surgery and radiation are documented poorly. METHODS The clinicopathologic features and disease outcome for 1225 patients with localized sarcoma who were treated with conservative surgery and radiation were reviewed retrospectively. Actuarial univariate and multivariate statistical methods were used to determine significant prognostic factors for local control, metastatic recurrence, and disease specific survival. RESULTS The median follow-up of surviving patients was 9.5 years. The respective local control rates at 5 years, 10 years, and 15 years were 83%, 80%, and 79%. Factors predictive of local recurrence were positive or uncertain resection margins; tumors located in the head and neck and the deep trunk; presentation with local recurrence; patient age > 64 years; malignant fibrous histiocytoma, neurogenic sarcoma. or epithelioid sarcoma histopathology; tumor measuring > 10 cm in greatest dimension; and high pathologic grade. Freedom from metastasis at 5 years, 10 years, and 15 years was 71%, 68%, and 66%, respectively. Factors that were predictive of metastatic recurrence were high tumor grade; large tumor size (> 5 cm); and leiomyosarcoma, rhabdomyosarcoma, synovial sarcoma, or epithelioid sarcoma. The respective disease specific survival rates at 5 years, 10 years, and 15 years were 73%, 68%, and 65%. Adverse factors for disease specific survival were high tumor grade; large tumor size (> 5 cm); tumors located in the head and neck and deep trunk; rhabdomyosarcoma, epithelioid sarcoma, or clear cell sarcoma; patient age > 64 years; and positive or uncertain resection margins. CONCLUSIONS Soft-tissue sarcoma comprises a heterogeneous group of diseases. Prognostic factors for local recurrence, metastatic recurrence, lymph node recurrence, disease free survival, and disease specific survival are different, and optimal treatment strategies need to take this complexity into account.
